Why is everyone around me spoiled and I'm not?

I'm 14 year old. I live with my Dad, my mum and my 8 year old sister.
My dad has a job that pays a decent amount (£45, 000 - £55, 000 a year)
and my mum has a part time job (around £8, 000 a year)
My friends always get more things than me, such as the latest phones, pre ordering video games, lots of expensive clothes. I don't get hardly as much as them. It really annoys me, as one of my friends even lost his iphone 5.
They are all lazy and careless. They don't earn the things as they spend all their time sitting at a screen playing on their xbox's.
One of my friends lives with his sister, his mum and 2 cats. He is given free school meals because his mum has a low budget job. He is spoiled rotten! Why am I not given this much? Surely my family can afford it. My sister does not suck up the money, she practically shares my things. My dad does not use any of the money more than he should, neither does my mum.
Why can't I have a nice phone? Why can't I have nice golf clubs (play golf btw) why can't I have a huge tv in my room? Why? Please tell me. I don't understand it.

How to calibrate Night Sky 2 according to the actual sky I'm looking at?

I recently purchased the night sky 2 app on my iPhone 5 because we're constantly stargazing and quarrelling over which star is which. The app says to calibrate it we must move the phone away from any interference or move the phone in a figure of eight. Is there a way of using location services and the app to find stars using my current location?
